[0031] Please refer to Figure 1 、 Figure 2 and Figure 3 The indoor unit 100 includes a middle frame 110, a drive box 130, and an air guide plate 190. The middle frame 110 is provided with a through slot 111. The drive box 130 is mounted on the middle frame 110, and a portion of the drive box 130 extends out of the middle frame 110 through the through slot 111. The air guide plate 190 is mounted on the middle frame 110, and the air guide plate 190 is transmission-connected to the protruding portion of the drive box 130. The drive box 130 has a protrusion 131. An avoidance groove 112 is provided on one side of the middle frame 110 near the protrusion 131. The avoidance groove 112 is used to avoid the protrusion 131 when the drive box 130 is mounted on the middle frame 110.

[0032] In this embodiment, a through-slot 111 is provided on the middle frame 110, allowing a portion of the driver box 130 mounted on the middle frame 110 to extend out of the middle frame 110 through the through-slot 111. The air deflector 190 mounted on the middle frame 110 is transmission-connected to the extended portion of the driver box 130, thereby making the connection between the air deflector 190 and the driver box 130 more compact and saving space. A clearance slot 112 is provided on the middle frame 110, allowing the protruding portion 131 of the driver box 130 to be avoided when the driver box 130 is mounted on the middle frame 110, making installation of the driver box 130 more convenient and quicker.

[0033] Please refer to Figure 4 In this embodiment, an air outlet 113 is opened on the middle frame 110, and the driving box 130 is used to drive the air guide plate 190 to rotate to open or close the air outlet 113.

[0034] Please continue to refer to Figure 4 and Figure 5 In this embodiment, the middle frame 110 includes a base plate 114 and side panels 115 provided on both sides of the base plate 114. The base plate 114 is used to mount the panel. The air outlet 113 is provided on the base plate 114. A mounting groove 116 is recessed inwardly along the length direction of the base plate 114 on the outer side of the base plate 114, and the air guide plate 190 is rotatably mounted in the mounting groove 116. The avoidance groove 112 is provided on the base plate 114, and the drive box 130 is mounted on the side panels 115. A through groove 111 is provided on the bottom wall of the mounting groove 116. The through groove 111 is located between the mounting groove 116 and the avoidance groove 112. The mounting groove 116 is connected to the avoidance groove 112. The mounting groove 116 is recessed on the middle frame 110, and the air guide plate 190 is mounted on the outer side of the middle frame 110, making the installation of the air guide plate 190 and the drive box 130 more compact.

[0035] In this embodiment, two drive boxes 130 are provided, one mounted on each side of the base plate 115. The extended portions of the two drive boxes 130 are drivingly connected to the sides of the air deflector 190. The presence of two drive boxes 130 allows the air deflector 190 to rotate via the two sides, thereby reducing deformation of the air deflector 190.

[0036] In this embodiment, the two drive boxes 130 are installed in the same manner, and the following embodiment is described in detail with reference to the installation of one drive box 130 .

[0037] Please refer to Figure 2 and Figure 3 In this embodiment, the protrusion 131 is located at the portion of the drive box 130 extending out of the middle frame 110. The avoidance groove 112 is recessed from the outer side of the substrate 114 to the inner side of the substrate 114. The avoidance groove 112 is recessed from the outer side of the substrate 114 to the inner side, which can reasonably utilize the space in the middle frame 110, thereby making the installation structure of the drive box 130 more compact. The avoidance groove 112 and the installation groove 116 are located on both sides of the through groove 111. After the drive box 130 partially extends out of the through groove 111, one side of the drive box 130 faces the installation groove 116, and the other side faces the avoidance groove 112. The protrusion 131 is protruded from the side of the drive box 130 facing the avoidance groove 112.

[0038] In this embodiment, the avoidance groove 112 has a first opening 117 facing the through-groove 111 and a second opening 118 facing the extending direction of the drive box 130. The first opening 117 is connected to the through-groove 111. The first opening 117 and the second opening 118 are used to allow the protrusion 131 to extend into the avoidance groove 112 when avoiding the protrusion 131. The first opening 117 and the second opening 118 of the avoidance groove 112 can conveniently allow the protrusion 131 of the drive box 130 to extend into the avoidance groove 112 when avoiding.

[0039] Please refer to Figure 5 and Figure 6In this embodiment, a hook 133 protrudes from the driver box 130, and a hook hole 119 is provided on the side panel 115. The hook 133 is hooked into the hook hole 119. The avoidance groove 112 is used to avoid the protrusion 131 when the hook 133 is installed in the hook hole 119. Because the driver box 130 is installed on the side panel 115 through the hook 133 protruding from the driver box 130 and the hook hole 119 provided on the side panel 115, installation is simple and quick. At the same time, since the drive box 130 needs to be moved before and after the hook 133 is inserted into the hook hole 119 to allow the hook 133 to pass through the hook hole 119 and be hung on the hook hole 119, the avoidance groove 112 can be set to avoid the protrusion 131 of the drive box 130 when the drive box 130 moves, thereby avoiding the interference between the protrusion 131 of the drive box 130 and the middle frame 110, making the installation of the drive box 130 more convenient.

[0040] In this embodiment, two hooks 133 are protruding from the drive box 130, and the retaining sections 137 of the two hooks 133 are protruding in the same direction. Two hook holes 119 are provided on the side plate 115, and the two hooks 133 are respectively hung in the two hook holes 119. In other embodiments of the present application, the number of hooks 133 and hook holes 119 can also be one or more.

[0041] Please refer to Figure 5 、 Figure 6 and Figure 7 In this embodiment, the hook 133 includes a connecting section 135 and a holding section 137. The connecting section 135 is protruded from the drive box 130. The holding section 137 is protruded from the side wall of the connecting section 135, passes through the hook hole 119, and the drive box 130 abuts against one side of the side plate 115. The drive box 130 can move toward the protruding direction of the holding section 137 so that the holding section 137 abuts against the other side of the side plate 115. The avoidance groove 112 is used to avoid the protrusion 131 when the drive box 130 moves. With the drive box 130 abutting against one side of the side plate 115 and the holding section 137 abutting against the other side of the side plate 115, the drive box 130 can be stably installed on the side plate 115. Since the drive box 130 needs to be moved in order to allow the holding section 137 to pass through the hook hole 119, the hook 133 on the drive box 130 is aligned with the hook hole 119 of the side plate 115, and the protrusion 131 of the drive box 130 will move together during the movement of the drive box 130. Therefore, by setting the groove, it is more convenient to achieve the avoidance of the protrusion 131 during the movement of the drive box 130, thereby avoiding the interference of the protrusion 131 with the middle frame 110 during the alignment of the holding section 137 and the hook hole 119, making the installation of the drive box 130 more convenient.

[0042] Please refer to Figure 5 and6 In this embodiment, the retaining section 137 is protruded in the direction in which the drive box 130 extends out of the middle frame 110, so that when the drive box 130 moves in the protruding direction of the retaining section 137, the drive box 130 partially extends out of the through-slot 111. Protruding the retaining section 137 in the direction in which the drive box 130 extends out of the middle frame 110 facilitates better extension of the drive box 130 from the middle frame 110 during installation. In particular, the protruding portion 131 of the drive box 130 can be removed from the avoidance slot 112 after the driver box 130 is installed.

[0043] In some other embodiments of the present application, the holding section 137 is also protruded in the reverse direction of the middle frame 110 toward the drive box 130, so that when the drive box 130 moves toward the protruding direction of the holding section 137, the drive box 130 is partially retracted into the through slot 111.

[0044] Please refer to Figure 5 and 6 In this embodiment, the hook hole 119 includes a first slot section 121 and a second slot section 122, which are connected in sequence. The width of the first slot section 121 is greater than the width of the retaining section 137, facilitating easier insertion of the retaining section 137 through the side plate 115. The width of the second slot section 122 is the same as the width of the connecting section 135. The hook 133 can move along the first slot section 121 toward the second slot section 122, so that the connecting section 135 abuts the sidewall of the second slot section 122. When the hook 133 is located in the first slot section 121, the protrusion 131 is received in the avoidance groove 112. By setting the width of the second slot section 122 equal to the width of the first slot section 121, when the connecting section 135 moves to the second slot section 122, the sidewall of the connecting section 135 abuts the sidewall of the second slot section 122, thereby positioning and securing the drive box 130. When the hook 133 is located in the first slot section 121 , the avoidance groove 112 is used to avoid the protrusion 131 , making it easier for the hook 133 to pass through the first slot section 121 .

[0045] Please refer to Figure 5 and 6 In this embodiment, because the width of the first slot section 121 is greater than the widths of the clamping section and the connecting section 135, and the width of the second slot section 122 is equal to the width of the connecting section 135, a first guide slope 123 is provided between the first slot section 121 and the second slot section 122 to ensure smooth movement of the connecting section 135 from the first slot section 121 to the second slot section 122. During movement, the connecting section 135 moves from the first slot section 121 to the first guide slope 123, and then moves from the first guide slope 123 to the second slot section 122, thereby achieving a smooth transition of the connecting section 135 between the first slot section 121 and the second slot section 122.

[0046] Please refer to Figure 5 and 6 In this embodiment, to securely mount the drive cassette 130 on the side panel 115, a locking portion 139 is protruding from the drive cassette 130. A locking hole 124 is provided on the side panel 115. The locking portion 139 moves with the drive cassette 130 as it moves. Once the drive cassette 130 is in place, the locking portion 139 aligns with the locking hole 124, locking into the locking hole 124 and securing the drive cassette 130 to the middle frame 110. By securing the locking portion 139 in the locking hole 124, the drive cassette 130 is secured in a direction opposite to the direction in which the clamping section extends, thereby securing the drive cassette 130 to the side panel 115.

[0047] Please refer to Figure 6 In this embodiment, the locking portion 139 includes an extension section 141 and a snap-on section 143. The extension section 141 is protruded from the side wall of the drive box 130 and extends in the direction of the protrusion of the clamping section 137. The snap-on section 143 is protruded from the extension section 141 in the direction of the protrusion of the connecting section 135. The snap-on section 143 extends into the locking hole 124 to securely mount the drive box 130 to the middle frame 110. The provision of the extension section 141 facilitates deformation of the locking portion 139, thereby avoiding interference between the snap-on section 143 and the side plate 115. After the drive box 130 is moved into place, since the locking hole 124 is provided on the side plate 115, the snap-on section 143 will extend into the locking hole 124 under the action of the restoring force of the extension section 141. In this embodiment, the drive box 130 is fixed by extending the engaging section 143 into the locking hole 124 by utilizing the deformation of the extending section 141 , thereby facilitating molding and saving costs.

[0048] In some other embodiments of the present application, the extension section 141 may also extend in the direction of the protruding direction of the clamping section 137 or in other directions. It is only necessary to ensure that the deformation box can be aligned with the locking hole 124 after the drive box 130 is installed in place, and the clamping section 143 can be clamped in the locking hole 124.

[0049] Please refer to Figure 6 In this embodiment, the engaging section 143 is provided with a second guide slope 145. The second guide slope 145 is used to guide the engaging section 143 when the drive box 130 is pushed so that the engaging section 143 extends into the locking hole 124. The second guide slope 145 also allows the extension portion to deform slowly, preventing damage to the locking portion 139 due to excessive deformation. The second guide slope 145 is provided on the side wall of the engaging section 143 away from the extension portion 141. The end surface of the engaging section 143 is higher than the end surface of the drive box 130, so that when the engaging section 143 moves to the locking groove, the engaging section 143 returns to its original position and extends into the locking groove.

[0050] Please continue to refer to Figure 2 and Figure 7 In this embodiment, the drive box 130 includes a box body 147, a motor 151 and a transmission member 149. The hook 133 and the locking portion 139 are protruded from the box body 147. The transmission member 149 is installed inside the box body 147. The motor 151 is installed outside the box body 147. The output shaft of the motor 151 is in transmission connection with the transmission member 149, and the transmission member 149 is connected to the air guide plate 190. The transmission member 149 partially extends out of the box body 147 to form a protrusion 131. Allowing the transmission member 149 to partially extend out of the box body 147 makes it easier to connect the air guide plate 190 and the drive box 130, making the connection between the air guide plate 190 and the drive box 130 more convenient. At the same time, the installation accuracy of the air guide plate 190 and the transmission member 149 can be guaranteed.

[0051] In this embodiment, the drive box 130 further includes a connecting member 153. The connecting member 153 is mounted on the transmission member 149, and the transmission member 149 can drive the air guide plate 190 to rotate. One end of the connecting member 153 is connected to the air guide plate 190 to drive the air guide plate 190 to rotate.

[0052] Please continue to refer to Figure 2 and Figure 6 In this embodiment, the transmission member 149 is provided with a mounting portion 155. A mounting hole 157 is provided on the box body 147, and the mounting portion 155 extends out of the box body 147 through the mounting hole 157. The transmission member 149 is provided with a through hole 159. The connecting member 153 includes a fixing portion 161 and a connecting portion 163 that are connected to each other. The connecting portion 163 passes through the through hole 159, and a portion of the connecting portion 163 extends out of the through hole 159. The portion of the connecting portion 163 that extends out of the through hole 159 is connected to the air guide plate 190. The fixing portion 161 is connected to the mounting portion 155 to fix the connecting member 153 on the transmission member 149.

[0053] Please continue to refer to Figure 6 and Figure 7 In this embodiment, the fixing portion 161 and the connecting portion 163 are connected by a snap-fit ​​structure. A clamping block 165 is protruded from the side wall of the mounting portion 155. A clamping hole 167 is provided on the fixing portion 161. The clamping block 165 passes over the clamping hole 167 and abuts against the end surface of the fixing portion 161.

[0054] To prevent interference between the connector 153 and the middle frame 110 during installation of the driver box 130, the connector 153 is fixedly mounted to the transmission member 149 via a snap-fit ​​structure after the driver box 130 is in place.
